Abstract
The invention relates to methods and apparatus for synchronously digital interfacing communications components. The apparatus includes a device configured to transmit and receive differential signals. One set of differential signals includes a transmit signal and a receive signal, and another set of differential signals includes a clock signal and a synchronization signal. The combination of clock signals and synchronization signals form other signals having a variable period. The other signals are used to modify the set of differential signals including transmit and receive signals.
